袁隆平宣布成果:除掉水稻中的镉,食品安全有保障

2017-09-28 08:31:03   

近日,中国工程院院士、“杂交水稻之父”袁隆平宣布一项剔除水稻中重金属镉的新成果。

《湖南日报》9月25日消息,近日,在2017年国家水稻新品种与新技术展示现场观摩会(以下简称“双新会”)上,袁隆平宣布了一项重大成果:“近期我们在水稻育种上有了一个突破性技术,可以把亲本中的含镉或者吸镉的基因‘敲掉’,亲本干净了,种子自然就干净了。”

近年来,伴随着农业供给侧结构性改革对绿色种业提出的新要求,农作物的纯净度越发受到关注,特别是在许多土壤污染较重的地区,如何避免污染元素在作物中的代际传播,是育种家必须考虑的问题。此项镉元素剔除技术将扭转我国部分农作物重金属含量超标的趋势。
